Embodiment
With preferred embodiment the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of conventional diesel engine uses the device of vegetable oil, comprises fuel tank 1, diesel engine 29, between the oil transfer pump 5 on described fuel tank 1 and the diesel engine 29 through first oil pipe 2 and second oil pipe, 4 heat exchangers in series 3; Described oil transfer pump 5 links to each other with filter cleaner 7 by the 3rd oil pipe 6, described filter cleaner 7 links to each other with fuel pump 16 by the 4th oil pipe 8, described fuel pump 16 links to each other with oil sprayer 10 by high-pressure oil pipe 9, the 6th oil pipe 13, return tube 15 and the 5th oil pipe 11 are connected in threeway 12, described heat exchanger 3 is connected with water-heating valve 17, and described heat exchanger 3 links to each other with the pump entrance 20 of described diesel engine 29 by the 9th pipeline 19.
Further, a kind of conventional diesel engine uses the device of vegetable oil, also comprises first temperature detect switch (TDS) 26, second temperature detect switch (TDS) 27, storage battery 25 and indcution heater 28; Described indcution heater 28 heats described oil sprayer 10 and described high-pressure oil pipe 9 by described storage battery 25 power supply backs.
Further, the lubricant oil main oil gallery mouth 21 of described diesel engine 29 links to each other with described fuel pump 16 by the 7th oil pipe 22, and described fuel pump 16 links to each other with the oil sump of described diesel engine 29 by the 8th oil pipe 23.
Working principle of the present utility model is as follows: when ambient temperature during greater than 5 ℃, diesel engine 29 can directly start.Vegetable oil from fuel tank 1 through first oil pipe, 2 inflow heat exchangers 3, outflow heat exchanger arrives oil transmitting pump of diesel engine 5 through second oil pipe 4, through oil transfer pump 5 pressurizations, enter filter cleaner 7 from the 3rd oil pipe 6, filter the back and enter fuel pump 16 from the 4th oil pipe 8, be pressed into high pressure and enter oil sprayer 10 by high-pressure oil pipe 9, oil sprayer 10 oil spout immediately.The threeway 12 that oil sprayer 10 unnecessary vegetable oil flow on the fuel pump 16 through the 5th oil pipe 11, at this, according to the need of work of diesel engine, can flow into filter cleaner 7 from the 6th oil pipe 13, need not filter, can flow back to fuel pump 16 from the 4th oil pipe 8 and continue fuel feeding, if oil is unnecessary, then can flow back to fuel tank 1 from return tube 15, so design, directly flow back to fuel tank 1 with oil sprayer 10 oil returns and compare, can significantly reduce heat loss and the filtration resistance of fuel oil.After diesel engine 29 started, cooling liquid was carried out short circle in diesel engine 29, and temperature can rise very soon, utilize the water-heating valve 17 of diesel engine, the cooling liquid of heating is sent into heat exchanger 3, vegetable oil is heated, the aperture of control water-heating valve 17 makes the vegetable oil temperature at 50 ~ 60 ℃.The cooling liquid that flows out forms circulation through the pump entrance 20 of the 9th pipeline 19 inflow diesel engines 29.
When ambient temperature during less than 5 ℃, second temperature detect switch (TDS), 27 closures, 28 power supplies of 25 pairs of indcution heaters of storage battery are heated oil sprayer 10 and high-pressure oil pipe 9, fuel oil energy is normally atomized start diesel engine 29.When coolant temperature during greater than 80 ℃, cooling liquid first temperature detect switch (TDS) 26 disconnects, and stops heating.At this moment, 3 heating of vegetable oil heater via, diesel engine 29 can run well.For fear of diesel engine 29 fuel pumps 16 from independent lubricating system because of vegetable oil seepage in the pump housing, cause the lubrication system performance of fuel pump 16 to descend, lubrication system to fuel pump 16 is reequiped, draw one road lubricant oil from diesel lubrication oil main oil gallery mouth 21 and receive fuel pump 16 through the 7th oil pipe 22, directly fuel pump 16 is lubricated, lubricant oil flows back to diesel engine 29 oil sumps through the 8th oil pipe 23 then.
What describe in the above specification is embodiment of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, the person of an ordinary skill in the technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of model utility.
